engineering on two wheels

a bicycle engineering and design weblog
World Bicycle Relief has a second model.  The first model was a nice heavy-duty bicycle but apparently there were a few problems with quality from the manufacturer in India.  I am not sure if these are from a new factory but they sure are a new model.  The design seems to have a more mountain bike feel to it.  Here is a pic of the old Superbike model:

The Superbike looks pretty slick here.  Somehow I doubt that the intended users of the Superbike will have spare tires for the Zipp rims that this bike is sporting.  When I first rode one of these at SRAM Chicago, it was before Zipp was acquired by SRAM so it is possible that a special wheel was added to Zipp’s lineup so they could add their logo to the bicycle (it was a raffle prize in this case).
From the World Bicycle Relief’s newsletter:
90,000 bikes worth of experience and five years of field-testing have led to World Bicycle Relief’s new Buffalo Bicycle models. These machines bring a new level of quality, durability and function never before seen in their class. Stay tuned for more on our new bicycle designs and how they take the Power of Bicycles to the next level.

and dutch has launched their North American operations.  I love their bikes — I am thinking about ordering up one of these:

                                           

The bicycles are shipped via a courier directly from the Netherlands about 90% assembled.

Küat Bottle Lock

Küat (pronounced Koo-at) Racks from Springfield, MO is launching a new product in November.  They developed a cable lock system that coils conveniently into a water-bottle shaped housing that fits neatly in the water bottle cage on most bicycles.  It looks like a simple storage method for some simple low-level security.

From the Küat website:

I cannot help but be reminded of this classic scene from PeeWee Herman’s Big Adventure:

While 5 feet is not an endless supply of cable, it should be enough to go around an animatronic clown at least once.

S&S Bicycle Torque Couplings

I just learned about these couplings made by S&S Machine:

                                                     

Frame builders can use these on new or existing frame to permit them to be taken apart.

Coupling

They are installed in-line with the top tube and the down tube to form a quick release so you can make your frame collapsible.  In the S&S Machine’s words:

“A bicycle manufactured with this system is ultra strong yet lightweight (two BTCs™ add only 8 oz. total to a typical road bike) and it feels exactly the same as a bicycle built without BTCs™. There is no added frame flex and the BTC™  is absolutely silent!”

GM taken down by Giant

Earlier this week the lovely advertisement department at GM started a campaign focused on selling cars and trucks to college students and recent grads at the expense of bicycles.

GM ad via thegoat.backcountry.com

Apparently a new Chevy (or a Buick if you happen to be 95 years old and freshly graduated) will help you succeed in life and get you the girl of your dreams.  While a lot of people are angry about the advertisement and find it offensive, I think it is all about the context in which it is viewed (in this case, viewed in a light different from that in which GM would like).  The image of a cyclist hiding his face from the woman in the car says to me that the cyclist is shunning the driver and avoiding making eye contact with someone with whom he has a very different opinion and very little in common; she may be pretty but he would not sacrifice his transportation choice just for a good-looking face.  Admittedly, this is a pretty far-fetched view and obviously not what GM or pretty much anyone else would see in the advertisement.

The clever staff at Giant Bicycles launched a response campaign the next day. Giant matched the tone, they matched some of the fonts and they seem to have struck a chord with GM as GM has since pulled the original advertisement.  Here is the Giant version:

I wish they would have matched the main headline font.  Maybe they have a corporate standard that they are required to use?

The Lords of the Chainring

My copy of The Lords of the Chainring arrived today.  It is an eight chapter text written by William Patterson, Emeritus Professor at California Polytechnic University to go along with a course he taught for many years on single track vehicle design.  It looks like it should be a good read.  I will post more after a thorough read.
